I still had my diagnostic plugs together under the dash. Would this prevent it from starting or can it run with these together?

So I took my IAC valve off and cleaned it well with carb/choke cleaner and checked the resistance between contacts as my Hayn manual suggested. Was wondering if there is someway of putting 12v to it and seeing it move? cleaned my MAF too and checked all the vacuum hoses I could as best I could. took the air filter out to clean it, didn’t put it back in yet. But tried to start it and it just cranked over, no start. This is with my original MAF that was working fine except for the random stall and easy restart like in a parking lot.

My 1990 Subaru Legacy has 198k mileage. for the longest time I have had issues with it stalling at low idle, mostly when letting the gas off in parking lots. I recently decided to try and address this, per the recommendation from a local mechanic, and switched out the MAF. after approx two weeks From changing out the MAF I started having issues with the car stalling while driving. Driving home one day, car started revving funny at a light then died. Restarted, drove a little, then died. Almost acting like it was out of gas. Which is what I honestly thought was the issue. I Drove as far as I could before it stalled and wouldn’t restart. After approx ten minutes, tried to restart, turned right on and I drove to nearest gas station to fill up. Continued on fine and made it home. No issues for the next day and half or so. flash forward a couple days. Turned my car on after work to warm up. After it warmed up it stalled. Tried to restart and wouldn’t. Let it sit ten minutes and it started right up. Drove as far as I could and it did the same thing. Stalled, let it cool some, restarted. Eventually it stalled and wouldn’t start. Next day came back to get car, started right up and drove it home. tried switching back to my old MAF and problem still persisted. Tried to disconnect battery to reset ECU and it wouldn’t even start now. pulled the codes and come up with: 24, air control valve inoperative (Abnormal signal produced in monitor circuit 35 Canister purge solenoid valve iniperative Now I’m wondering if either of these could realistically be at fault? I checked fuel at the filter, seems to be pumping. Based on the way it’s acting, it seems like a fuel issue either from pump or mixture at MAF, I have a k and n filter that probably needs to be cleaned. Could that be contributing to an issue? Or oil on the MAF sensor? hmmmmmmmmm....
